Porphyrochroa manauara

sp. nov.

Porphyrochroa manauara  sp. nov.

(Figs. 10 a –i; 18 j; 20)

Diagnosis: P. manauara  sp. nov. Is closely related to P. simplex  sp. nov. due to the semi-circular shape of epandrium, and widespread setae clothing the hypandrium. It differs due to the absence of a lateral posterior projection on sternite 8 and simple apex of the hypandrium.

Description. Male: body length 2.4 mm; wing length 2.1 mm.

Frons and face shiny brown. Frons slightly narrower than width of anterior ocellus, sides subparallel, with four proclinate setae. Face slightly longer than frons and length about twice width of frons. Proboscis light- FIGURE 10.

yellow, length equal to height of head. Palpus brown, with one small and almost apical seta. Ocellar tubercule with light-yellow ocellus; two proclinate slender and long ocellar setae; short proclinate postocellar setae. Antenna with scape, pedicel and flagellum brown; scape and pedicel medially verticillate; flagellum about four times longer than scape and pedicel combined. Postcranium shiny brown, with distinct brown setae and gray pruinescence; pair of convergent vertical setae; postocellar setae distinct, arranged in complete single series with dorsal setae stronger. Gena and postgena with brown to black setae and sparse gray pruinescence. Thorax light-brown, with pprn lobe yellow and with gray pruinescence conspicuous to transverse suture. Thoracic setae: 4 slender ktg; 4 sctl, larger internal pair; aprn broken; 2 prepm; 3 pprn; 2 acr; 5 dc, hind setae larger; 1 spal presut; 1 psut spal; 2 npl; 1 pal. Foreleg yellow, with tarsi brown; mid and hind legs with coxae, trochanters and basal fifth of femora yellow, remaining segments brown; hind tibia and mid basal tarsomere with long dorsal setae. All legs with short distinct setae, with setae longer distally. Wing hyaline with apical spot and inconspicuous pterostigma; anal lobe wide ( Fig. 18View FIGURE 18 j). Halter with pedicel yellow and knob brown. Abdomen shiny brown, with metallic blue luster in diverse light incidence angles. Sternites brown. Tergite 7 with pair of posteroventral protuberances (Fig. 10 a); tergite 8 shorter than former ones (Fig. 10 a); sternites 6, 7 and 8 with lateral posterior projection (Fig. 10 b); sternite 7 inclined in lateral view (Fig. 10 c). Terminalia: hypandrium superiorly narrower (Fig. 10 d), with setae posteriorly (Fig. 10g). Elongate cercus in lateral view (Fig. 10 d); in dorsal view with bifid apex and with internal ventral downward projection in dorsal view (Fig. 10 h). Epandrium posteriorly round, with distal setae (Fig. 10 e). Ejaculatory apodeme with three projections in anterior view (Fig. 10 f); subepandrial sclerite with base and apex with proportional sizes (Fig. 10 i).

Female: Unknown.

Holotype condition: aprn setae broken; left wing mounted on microslide in Canada balsam; abdomen within microvial containing glycerin. Microslide and microvial pinned attached to specimen.

Variation: ten specimens with short setae on all legs.

Etymology: The specific name in reference to the name of the city of Manaus, the type-locality.
